While it is easy to look for cheap tires on sale over the internet most people are not sure about the consequences of driving with flat tires. Does driving with flat tires have any effect on your car and the tires themselves? According to auto mechanics driving with flat tires could cause damage to the tires and to the wheels themselves as there is a possibility that the wheels might be contacting the ground causing it damage. Driving with flat tires also causes more stress on the suspension as the tires that are properly fitted do tend to absorb a lot of vibration and shock. If you drive your car with flat tires all this vibration would then be absorbed by the suspension. However other than the tires and wheels and to some extent the suspension it is unlikely that driving with flat tires is going to cause any damage to the rest of the car.
